A linear multichannel detection system for billing by spectrum convolution applicable in telecommunications systems, capable of detecting the metering pulses in a signal sent from a telephone exchange to the subscribers, multiplying the signal by a specific signal generated by the system and measuring powers corresponding to the signals resulting from the multiplication, in such a way that a power measured with a value greater than a predefined threshold value indicates detection of the pulse. The invention likewise refers to an access system including the detection system.
